Analog CVBS, AHD, CVI and TVI Camera Connection Explained

Difference between CVBS, AHD, CVI and TVI camera connections

AHD Camera

AHD stands for “Analog High Definition” and means an analog closed-circuit television video surveillance standard that uses a coax cable to transmit HD 720P and 1080P video from a security camera to a security camera recorder DVR (Digital Video Recorder).

HD TVI Camera

HD TVI cameras, also known as High Definition Transport Video Interface cameras, provide high-quality, high-definition video surveillance solutions up to 4K.

HD CVI camera​

HD CVI (High Definition Composite Video Interface) is an analog transmission standard-based over-coaxial cable delivering two HD video formats: 1920H or called otherwise, Full HD 1080P (1920×1080) & 1280H or called otherwise 720P (1280×720) through progressive scanning.

CVBS camera

CVBS stands for “Composite Video Blanking and Sync” (you can find a more detailed theoretical explanation on Wikipedia). It is a conventional analog signal delivered through an analog BNC connector. It can also be delivered through an RCA connector or other types (older cameras sometimes used a PL-259 connector). The CVBS  signal can support a maximum 960H video resolution. 960H represents the number of horizontal pixels in a video signal transmitted by a camera or a security camera digital video recorder (DVR). 960H represents 960 x 576 (PAL) or 960 x 480 (NTSC) pixels; you can compare it with the lower D1 resolution, which provides 720 x 576 pixels (PAL), or 720 x 480 pixels (NTSC).
